~~ August 11, 2008 To: Orange County Planning Board Attn: Tom Altieri, Comprehensive Planning Supervisor Orange County Planning and Inspections Department 306-F Revere Rd., PO Box 8181 Hillsborough, NC 27278 From: Ken Terlep 4601 Eno Cemetery Road Cedar Grove, NC 27231 Subject: Comprehensive Plan Update: Request that Information Pertaining to Lake Orange is documented in Table 6-5 Dear Mr. Altieri: I am writing to request changes to Table 6-5 in the Comprehensive Plan scheduled to go to Public Hearing on 8/25/08. Specifically, I ask that the following_information be added to the table: • The 20 Year Safe Yield for Lake Orange should be shown as 1.0 MGD • The storage amount (useable for Lake Orange is 409 MG Additionally, the footnote 59 should be removed as it }s not accurate. Lake Orange is currently a source of raw water for multiple users and not just the Town of Hillsborough. Lake Orange must be recognized as an important and independent source of raw water for multiple users in the county and its capability /limitations documented. It is understood that the Town of Hillsborough is the greatest user of water from Lake Orange but allocations are currently in place for significant withdrawals by Orange-Alamance Water System as well as by Piedmont Minerals. The current O-A withdrawals are smaller than its allocation and the Piedmont Mineral withdrawals are very much less than its allocation. Basis for Request: I have spent considerable time over the last few weeks investigating the WFER design and analysis including the accepted 20 Year Net Safe Yield of 1.8 million gallons per day. I used the same methodology and common or extrapolated assumptions to calculate the 20 Year Net Safe Yield for Lake Orange which is assessed to be 1.0 Million gallons per day. I have presented the methodology, assumptions and results to Mr. Paul Thames and Mr. Kevin Lindley of Orange
